Signs of a Blown Out Car Amp

Well, there could be plenty of signs that could be quickly manifested by the sound as you turn on the stereo system.

Some of these signs are the following:

  • There is no sound though you have already turned on the audio system.
  • There is a noticeable sound distortion.
  • The stereo system would begin making bizarre sounds like a farting sound.

If these signs are noticed, you should be aware that the car amp is the one responsible. There could also be chances wherein other components in the car audio system cause the said distortions, but still, the car amp has always something to do with it.

Reasons and Causes Behind

There could be cases wherein you wonder that you also have audio systems at home too. And so, why the said audio system doesn’t blow out most of the time. Well, there is a significant difference in between a car audio system and a home audio system. And bear in mind that the car audio system would work under different environment.

There is a need for it to face issues including the following:

  • Temperature extremes
  • Various stresses on the road
  • Continuous vibrations

With regards to home audio system, it doesn’t bear such extreme conditions. And these are the reasons why the car amp blows out a lot frequently than the one at home.


How to Tell If Your Amp Is Blown: Try These Different Ways

And you might be wondering of ways on how to tell if your amp is blown at this moment. Well, there could be troubleshooting ways that will help you on how to figure it out.

Here are the different ways on how to do so:

Is the protection mode of the car amp on?

Before you assume anything with regards to the situation, you need first to check the protection mode of the car amp. There is this provision that once the amp encounters something wrong, then it would switch to the protection mode.

The said suspicious situations would include the condition of the wires of the speakers are touching one another and into short-circuiting. If you put it in a protection mode, car amp will avoid any electrical damage in the system.


​Is the blue wire connected to the right part of the wiring harness?

​This blue wire is being used in the car audio system as for accessing the amp remotely once the power is turned on. Once it is not properly connected to its right place, then it would fail to offer adequate voltage to the amp.

So, you might think that the amp isn’t working only to find out that it is not the case.

​Do you find fuse blown out already?

​Indeed, every car audio system would include the fuse to prevent damage to the sound system when there is a short circuiting. It is being placed in between the power line. Once the fuse is blown out, then there would be any supply of power to the amp, and it wouldn’t turn on even if you have already set on the power supply.

​So, there is a need for you to check the small metal wire into the fuse and once you find it snapped, there is a need to replace the fuse with a new one.


​Have you checked the input and output of the amp?

​The input of the amp comes from the head unit. So, if you are bothered about how to check if it is just fine, things could be straightforward. There is just a need to disconnect the RCA cables and then connect the new set that works correctly.

​After being replaced, if the amp could be turned on quickly, you have to change it. However, if you get the input from an edge and not from the others, then there could be some issues in the head unit.

Now that everything works fine, you have to disconnect the current speakers and connect the new set. Once the amp gives the right output, it will work well too. If this is the case, you would need new speakers for the audio system and not for the car amp. You might consider the best 6x8 car speakers.

You need to ask yourself these questions in order to identify whether the car amp is blown and so you could come up with the best way to resolve the issue.
